So I read that CD quality is definetly better than mp3 (don't know about wav though). I have a giant stereo set: huge amp, 2 tall speakers, 2 short ones for side, and 1 center. it is connected to my computer with an SPDIF optic cable - but to an 8 year old mobo, no sound card - which might be the problem. So I grabbed some album I got on CD, played it, compared it to YouTube - but it sounds exactly the same! Is it my mobo/soundcard, or should I play it on some DVD player?
